VerticalGridFragment Endless scroll

I'm creating android tv app but I don't know how to implement endless scroll in Verticalgridfragment, i use ArrayObjectAdapter, can someone help me do that?

I'd love to give you a full answer with oodles of code samples but I'm not at my work computer. Basically you'll implement the onItemSelected listener in your Browse/RowsFragment (it should be something like setOnItemViewSelectedListener() from your fragment).
Then you do a check to see if the currently selected element is within 5 or 10 or 15 elements from the end of the list. If it's within that threshold, then make the request for the next page of your list and call addAll() on your adapter when you get the next page. You can optionally show a "loading card" while the next page request is in flight and remove it when you get your data.
I based my implementation off of this open source project - while it's not perfect it should be enough of a code sample to get your started.

ViewPager - Hide number of pages

I'm building my Android App using Viewpagers, and I built a ListView that takes 8 seconds to show the full Items.
The page doesn't update the view automatically, thats why the Listview appears empty when it is shown for the first time.
So, I was thinking about creating a new page called loading, and hide the page with the listview, and only show it when the Listview items are already there.
To do that, I would like to know how can I hide pages.
I tried to use an Handler and change the number of pages after 8 seconds, but it didn't work, can you guys give me any idea of how can I do that?
Thanks.

You shouldn't create a new page called loading,it is not a good way to solve it. You can u get data in oncreat first time,then update data by a timeror handler+timertask and so on.

any tutorial on how to add items to listview when scrolling down, showing progress item in the meanwhile?

I have a listview whose data is taken from internet.
Data is a list, a long list, so I'd like to display the first, say, 10 results.
If user scrolls down I'd like a progressbar to appear at bottom, while I ask for the next 10 results to server, then remove progressbar and add the new 10 items.
I see this behaviour in the facebook app, can you point me to a tutorial to do something similar?

First, here is a tutorial for a never-ending ListView:
Android tutorial: Dynamicaly load more items to the ListView ( Never Ending List! )
I've used this in my application and it works flawlessly.
Secondly, this tutorial will teach you how to grab data from the internet and display it in your ListView: Android Custom ListView with Image and Text
Combine both of them together and you get what you need [Provided you have the basic knowledge of Android programming. Goodluck ;)]

Android ListView with an incrementally built ListAdapter

I am trying to figure out the right architecture for a list view that loads information from an http endpoint. My problem is that the information to be displayed has both text and image content. If I only load the text content the the UI is very responsive but if I also load the image content then it takes a few seconds for the list to be populated. I parse the content as it comes in and build up a list adapter but what I want to do is build up the list adapter incrementally so that the user sees the information as it becomes available instead of waiting until the last item is processed before any information is displayed. Currently I do everything with the help of AsyncTask so I'm aware of threads and how they can be helpful so I'd like to know how other people have worked around the issue of displaying list based information as quickly as possible.

So this solution doesn't incrementally build the ListView but if the text information comes quickly as you mentioned I think it might help:
Lazy load of images in ListView
Basically this solution will place a stub image in the ImageView until the desired image is finished downloading.

It is not only about loading images as far as i understand your question. Please look at "Implementing a Dynamically Loading Adapter (Endless List)" tutorial: http://codinglines.frankiv.me/post/14552677846/android-implementing-a-dynamically-loading-adapter

Getting stuck implementing pagination in Android

I have the following requirements.
I am displaying 10 items in a ListView in which each List item displays 2 text views & one thumbnail image . I have coded to display the images asynchronously , since I need to fetch the images using url. The data for the list item is being fetched from server. In the response , I get the information whether any more pages are available for display.
After the user scrolls to the 10 items , I need to call the webservice to fetch the next 10 list of items from the server . When the user scrolls to the 10 th element of the first page , a small progress dialog is displayed at the end of the screen & information is fetched from the server & the view is updated . Also if the user scrolls up , new call to the webservice is not made to the server & the display contains all the list items.
I received few suggestions but am unable to implement the pagination .
Kindly help as I am stuck on this problem for more than 3 weeks.

You might try my EndlessAdapter and see if either it can solve your problem directly or give you ideas of how to implement your own take on the concept.
